I. will; not ldescribe thev connectionsbetween the 'shaft-L 4Q and theshaft42 .because they are exactly theshaft 32. This shaft 42 has a bearing in a bracket 44 depending from thetop of the window casing.

All these gears have the same numbeil of teeth but an advantageousleverage is secured by having the gear 29 made with teeth of doublelength and causing the driving gear 2S to mesh with it at a greaterdistance from the center than the driven gear 36. Thus, the two shafts32 and 42 will be rotated at the samerspeed, although this provides asort of differential to transmit an excess of power caused by any undueresistance from one shaft to the other and equalize the strain.

The two shafts 32 and 4Q are provided with screw threads of oppositepitch but of course the same number of threads to the inch. Each ofthese is provided with a nut 45 adapted to be moved along the shaft bythe rotation of the latter. Each nut is swiveled by a horizontal pin 46to a bracket 47 of right angular construction to ht around the corner ofthe sash. The bracket constitutes half of a hinge and has a vertical.

pivot stud 48 at the outer end of the projecting part which, in turn, ispivoted to a right angle plate 49 constituting the other half of thehinge and secured around the corner of the sash 11. These two pivotstuds 4S arer in vertical alignment and the two hinges thus formednecessarily operate together and equally. The casing and sash arerecessed at 54 to receive the parts 47 and 48. The controlling arms 14and 18 being constructed exactly alike and located in exactlycorresponding positions also help to control the motion of the sash sothat it will always move equally at top and bottom. The gear arrangementinsures an equalization of strain between the top and bottom andtherefore, even after long usage, the two operating mechanisms willcontinue to operate the sash equally at the top and bottom. Thereforethe device is not likely to get strained at either place or to bind.

For the purpose of preventing undue strain on the parts when the windowis start-- ing to open, I provide on the stationary part of the sash atthe top and bottom a plate 50 having a projection provided with anupward guide 51 which is longitudinal with respect to the closed windowand is intended to operate only while the crank handle 22 is beingturned to take up any looseness of the gears before the sash begins toturn. It

, might be explained here that the first motion of this crank movesoutwardly the two nuts `4.5 slightly before the sash can commence toturn. This action takes place during about a quarter of a turn of thecrank and it might 1tend to swing the hinge member 47 and bind the partsif no guide were provided. Also in closing, a perfectly tight closure isdifficult to secure at this point for the same reason. Therefore thisshort guide 51 projects upwardly at the bottom behind the hinge part 47and insures longitudinal motion at the end of the closing and beginningof the opening motion. Therefore the motion of the nut 45 and itsbracket 47 slightly to the left to the position shown in Fig. 2 fromthat in which it is up against the head of the hub 32 will not bind thesash but will release it. Also, it will be noticed that when the sash isclosed the outer end of the sash comes up into perfectly closed positionbut the inner end has a tendency to move outwardly slightly. But duringthe last quarter turn of the crank 22 this guide 51 comes into actionand firmly holds the inner end of the sash in tightly closed position.This construction is formed at the top and bottom and the same referencenumerals are applied in both places.

In this way it will be seen that a construction is provided which is notunduly expensive but which will positively actuatc the shaft both at thetop and the bottom, will positively close it at the pivot edge, keep itclosed until the crank is turned, and prevent its moving outwardly atthe beginning of the turning of the crank and binding. Furthermore, bythe gear arrangement the strains at the top and bottom are equalized andtherefore the wear is the same in both places. The window does not swingon alixed pivot but on a movable one so that it will move along the sashat the pivot end and the sash will be located part way between the twosides of the casing when it is open so that the window can be washed onboth sides from the interior of the house.

Although I have illustrated and described only one form of the inventionI am aware of the fact that modifications can be made therein by anyperson skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore I do not wish to belimited to all the detailsv of construction herein shown and describedbut what I do claim is 1. In a. sash operating device, the combinationwith a casing and sash, of two screws located constantly in horizontalposition at the top and bottom of the casing for simultaneously andequally moving the top and bottom of the inner edge of the sash awayfrom the adjacent edge of the casing, means for actuating said screws,and means-acting directly on the top and bottom of the outer end of thesash for swinging it outwardly.

2. In a sash operating device, the combination with a window casing andsash, of a pair of arms one located above the top of the sash openingand the other below the bottom of the sash opening, both pivoted to thecasing at points intermediate the inner and outer surfaces thereof andpivoted at their' outer ends respectively to the top and botto-1n of thesash at points adjacent to the inner edge thereof, a pair of hinges, onehinge member of each hinge being xedly mounted on t-he inner side of thesash at the top and bottom and extending around the edge of the sash andhaving a hinge pivot located along the edge of the sash, the other twohinge members being connected with the hinge pivots and having a partextending therefrom inwardly toward the inside of the casing and anotherpart `at right angles thereto parallel with the front face of thecasing, and means for sliding the latter along the casing parallel withthe front surface thereof.

3. In a sash operating device, the combination with a window casing andsash, of means located at the tQp and bottom of the casing forsimultaneously and equally moving the inner edge of the sash away fromthe adjacent edge of the casing and swinging the outer end of the sashoutwardly, said means comprising an arm pivoted to the casing and to thesash a crank, a pair of right and left hand screws, one located at thetop of the casing and the other at the bottom parallel with each other,a vertical shaft having gears at the top and bottom, gears on thehorizontal screws meshing with the gears on the vert-ical shaft, andmeans for turning the vertical shaft from the crank.

4e. In a sash operating device, the combination with a window casing andsash, of an arm pivote'd to the casing and pivoted to the sash, a hingecomprising two members, one being ixedly mounted on the inner side ofthe sash and extending around the edge of the sa'sh and having a hingepivot located along the edge of the sash, theother hinge member being`connected with the hinge pivot and having a part extending therefrominwardly toward the inside of the casing and another part at yrightangles thereto, and means for sliding the latter part along the casingparallel with the front surface thereof.

5. In a sash yoperating device, the combination with a casing and sash,of an arm pivoted to both for swinging the sash, a hinge having twomembers, one fixed to the edge of the sash and the other slidable alongthe casing, and having an offset at the end at which it is pivoted tothe other hinge member on the edge of the sash, a nut swiveled to thesliding part of the hinge, and a screw passing through the nut foroperating it.

6. In a sash operating device, the combination with a casing, a sash andan arm pivoted to both for swinging the sash, of a hinge having twomembers, one fixed to the edge of the sash and the other slidable alongthe casing, said members both having an offset at the end at which theyare pivoted together by a pivot pin, a nut swiveled to the sliding partof the hinge, a screw passing through the nut for operating it, and aguide plate fixed on the side of the casing and having a hook projectingunder the sliding member in certain positions thereof for preventingside play of the sliding member at the time when the sash is closed ornearly closed.

In testimony whereof have hereunto afixed my signature.
